Range of timing products target 4G LTE and small cells
The latest LTE-Advanced features — such as Enhanced Inter-Cell Interference Coordination (eICIC), Coordinated Multipoint Transmission (CoMP), Carrier Aggregation (CA) and Multi-Media Broadcast over a Single Frequency Network (MBSFN) — require an even higher degree of precision. Carriers are making significant investments in small cells, LTE-A and Heterogeneous networks to increase capacity and coverage. Network synchronization is a must to achieve both objectives.
Trimble offers timing products that are ideal for a wide range of small cell synchronization applications. The devices provide increased holdover capabilities and more robust signals with multi-constellation GNSS technology to sync wireless networks more efficiently.
The Mini-T™ GG Disciplined Clock is a multi-GNSS (GPS and GLONASS) embedded module, optimized to generate precise 10 MHz output and pulse per second. It utilizes the latest in GNSS technology, combined with a precision ovenized oscillator for near atomic clock precision timing. The Mini-T GG provides 24-hour holdover capability and is suitable for pico and microcells.
The Trimble 360™ multi-GNSS receiver is designed to cover the full spectrum of small cells — residential femtocell to rural microcell. These timing products support GPS, GLONASS and BeiDou systems, and are Galileo-ready. In addition to full constellations, the 360 products support Satellite Based Augmentation Systems (SBAS) and the Asian Pacific Quasi-Zenith Satellite System (QZSS).
The compact, surface mount ICM SMT 360 timing module, measuring only 19 x 19 mm generates a precise 10 MHz reference clock for synchronization of residential and enterprise femtocell networks. It provides holdover capability, which allows the module to extend the availability of reference timing outputs.
The Resolution SMT 360 is available in the same 19 x 19 mm form factor, and provides a pulse per second that provides nanosecond accuracy to any application requiring precision time reference such as wireless networks, utilities and digital broadcasting.
The Trimble Mini-T GG disciplined clock, ICM-SMT 360 module and Resolution SMT 360 timing module and starter kit are available now. The Trimble 360 multi-GNSS receiver is expected to be available in January 2015.
